The remains of the world’s oldest planned city may crumble to dust in twenty years if action isn’t taken, the Telegraph reports.

Mohenjodaro, a 5,000 year-old city in Pakistan, is under threat from extreme temperatures and monsoon rains, which leave deposits of salt on the unbaked clay bricks that were used to create its buildings. That salt leeches out any moisture in the bricks and slowly turns them to dust.

A crew of workmen is coating the ancient structures with salt-free mud, but there are far too few people on the job and very little money.

The Bronze Age city, which is a UNESCO World Heritage Site, was founded around 3,000 BC and shows a remarkable amount of urban planning. There were toilets in every house, separate water systems for drinking and sewage, roads laid out on a grid system, a large communal bath shown in the above photo, and a communal granary. It was the center of the Indus Valley civilization and traded as far away as Mesopotamia, using a set of standardized weights and measures to regulate commerce.

UNESCO officials met with Pakistani archaeologists last week to draw up a plan to save the site, which includes burying some of the most threatened structures. It remains to be seen whether Pakistan’s government, strapped for cash and stuck in a grueling war with the Taliban, will foot the bill.

I visited Mohenjodaro back in 1994 when Pakistan was safer to visit than it is now and found the place to be enchanting. The layout can be clearly seen and it almost feels like you’re in a living city. It would be a shame if such a landmark of human development disappeared.

The proposed route is the brainchild of Tahir Khokher, transport chief for the Mirpur region of Pakistan-controlled Kashmir. The route starts in the northern English city of Birmingham, where many Pakistanis from the Mirpur region live, and runs 4,000 miles through Europe, Turkey, and Iran before reaching northeastern Pakistan and ending at Mirpur.

The problem, of course, is the route itself. It runs straight through Iran and continues on to Quetta in Pakistan, which is a popular hangout for Al-Qaeda. The Kashmir region, which has been the scene of conflict between Pakistan and India since those nations were formed, isn’t exactly the safest place in the world either. A recent survey found Pakistan the seventh unfriendliest country in the world, right after Iran.

On the other hand, a trip will only cost £130 ($200), making it an awesome budget travel option for the adventurous.

The Daily Mail quotes a Birmingham Minister of Parliament expressing concerns that the route could be dangerous. There is also the question of whether it would be used as a low-cost conduit for terrorists.

Khokher says the problems with permits should be ironed out within a month. Stay tuned for more news about the 12-day bus ride through one of the toughest regions in the world.
